new and useful Improvements in a High- Speed Spindle; and Ido herebydeclare the following to bea full',l clear, and exact description of theinvention, such as will en'- able others skilled in the art to which itappertains to make and use the same.

The object of the invention is to provide a relatively simple andeiiicient construction and mounting of a spindle for high speed work, asfor example up to one hundred thousand revolutions per minute, -and de-`signed while minimizing friction and thus overcoming the disadvantagesof overheatand andV wearing to permit of the assembling and disassemling of the elements with facility, to provide 'foreliminatin lonitudinal or axial vibration as well as atera vibration, and to providefor the construction of the several parts or elements at a moderatecost, and more es ecially to increaseA the ecienc and durability of theball bearings to avoi the necessity of repeatedly renewing` or replacingthe parts thereof; and with these objects in viewthe-invention consistsin a construction and combination of parts of which a preferredembodiment is shown in the accompanying drawings, wherein Figure 1 is alongitudinal sectional view of the spindle construction.

Fig. 2 is an end view of the same.

Figs. 3, 4, 5, 6 and 7 are transverse sectional views respectively onthe planes indicated by the lines 3-3, 4-4, 5--5, 6-6 and 7`7 ofFig.`1.A

Fig. 8 is an enlarged edge view of the pro-V peller wheel.

Fig. 9 is a detailed sectional view through a portion of the blade orbucket carrying peri hery of the wheel.

ig. 10 is an enlarged sectional view taken longitudinally of one of thebearings on the plane of Fig. 1.

Fig. 11 is an enlarged longitudinal sectional view on the planeindicated by the line 11-11 of Fig. 1.

Figs. 12 and 13 are respectively plan and side views of the nozzleenlargsled. Fig. 14 is a side view of t e spindle detached. Fig. 15 isan enlarged detail view of portions of a set of the ball bearing conesto 1nably bein Speoication of Letters Patent. Patented Sept. 27, 1921.

dicate the relative angles of the bearing sur screw jointed together asat 22, said tubular body having a head 23, a propeller 24 conslstmg of asolid disk having a stem or drive shaft 25, a spmdle 26 connected withthe drive shaft and carrying a`quill 27, and a nozzle 28 adapted to beconnected with the source of air or other fluid pressure and attached tothe head 23 for communication with a plurality of'tapered jet passages29 formed 1n thehead for discharge of the fluid lnto the peripheralblades or buckets 30 of the propeller. Attached to land carried by thehead of the body member of the casin 1s a tubular exhaust 31 in whichthe prope ler is located and the blades or buckets of the latter are ofarcuate form as indicated in detail in Flgs. 8 and 9 with peripheralstuds 32 for engagement with openings 33 formed in a housmg band 34-embracing the eriphery of the propeller and preferablyfldrmed insections. i l

The bore of the body member of the casing is shouldered as indicated at35 at the end adjacent to the plane of the propeller to form a seat forthe outer cone member 36 of a ball bearing, said cone member beingdouble beveled and disposed in facin relation with aninner cone member37 wlth the interposed balls 38, said .outer cone member also beingdouble beveled but preferably consisting of separate rings as indicated,said construction providing for a four point bearing-of eachanti-friction ball, and one of the bevels of the inner cone memberprefer' at a different angle from the other, so t at in operation theballs receive a lateral rotary movement as well as a rotary movementparallel with the races. In

practice it has beenfound desirable to make the angles of the outer ballcone or race respectively at 20 and 24, so that in operation the ballsvreceive one revolution laterally or sidewise to every three hundredsixty (approximately) revolutions in the directlon parallel with theraces. This insures a uniform wearing of the balls and hence a greatervdurabillty and longer life and utility thereof while serving,particularly owing to the four point bearin of the balls upon the races,to prevent en wise or play losll moeioii besveeeii lie pares., The driveshaft oi' stem 25 elle propeller also extends through a second bearingleaving; a construction similar te above described and consiseiug of theiuiieiA wel este? cones or ball reces 39 and eel wieli iuerposed ballsel? the. oueer' cnes' speee freie ibi/ieee ef the fiest named beaiiii,by a spacing 'fing 22, and elle members "alie secend bearing areseeuredin the balai" bis-civ membero Jalie cesing by a ring Wliicli is bellow,having a eaviey iii E is a 'ele ei similar' abserbeni,
